I putting to together my bike, This will no doubt be the lamest question I have to ask? Right lever is front/ brake left is rear or do I have this wrong I have not cut anything yet

When you purchase a bike, the left lever controls the front brake, the right the rear. But if you prefer it the other way, it shouldn't be too big a problem. It is usually set up that way because most people are right handed, so they put the front brake on the weak hand so you don't accidentally grab it too hard--at least that was probably the logic, though many can testitfy to grabbing the front brake way to hard with their weak hand, anyway.
